What I want to do is have 1 12vdc square wave input, with a "splitter" that will alternate between 2 outputs, I want to do this electronically, and not with a Hall type sensor going high or low to reset

This thread is useless without more data.

A square wave can be easily generated, then add an inverter as the second output.
The next question is: what frequency?
Then there are a whole bunch of other questions.

Can't be for injectors. 12V is too much for them. Also pulse length is critical. The computer takes a basic pulse train and modifies the hell out of it according to sensor inputs.
